WebThe problem seems to be inherent as all the other existing results on memory-tightness are lower bounds and impossibility results. In fact, Auerbach et al.conjectured that a memory-tight reduction for [inline-graphic not available: see fulltext]security of Hashed-ElGamal KEM is impossible. We refute the above conjecture.
